Determine if a triangle with side lengths 8, 14, and 15 is acute, right, or obtuse

asambeis [7]

Answer:

Acute

Step-by-step explanation:

The Converse of the Pythagorean Theorem states that:

If $a^2+b^2 > c^2$ then the triangle is acute.
If $a^2+b^2 < c^2$ then the triangle is obtuse.
If $a^2+b^2 = c^2$ then the triangle is right.

The side lengths 8, 14, and 15 are given. We can assume the hypotenuse (or c) is the longest side length, so it is 15.

c = 15

It doesn't matter which order of the numbers are plugged in for a and b, so a and b will be 8 and 14.

a = 8
b = 14

Now we have to add $a^2$ and $b^2$ to see if the sum is greater than, less than, or equal to 15 (c).

$a^2 + b^2$
$8^2 + 14^2$

Calculate the rest of the problem.

$8^2=64 \newline 14^2=196$

$64+196=260$

We have to find what $15^2$ is before we can make a decision using the Converse of the Pythagorean Theorem.

$15^2=225$

260 ( $a^2+b^2$ ) is greater than 225 ( $c^2$ ). This means that the triangle is acute because $a^2+b^2>c^2$ .

Which function rule describes the pattern in the table?

lakkis [162]

The correct answer is B.

In order to prove which of the function rules provided is the one corresponding to the schedule represented by the table, the different y-values need to be sustituted in the function rules. Only the correct function rule will yield the corresponding x-value.

Let's prove that option B is the correct one

FUNCTION B y= 5x - 14

If x= -4 --> substituting: 5(-4) - 14= -20 - 14= -34 therefore, y= -34 CORRECT
If x= -1 --> 5(-1)-14 = -5 - 14= -19 therefore y= -19 CORRECT
If x= 2 --> 5(2) - 14= 10-14= -4, therefore y= -4 CORRECT
If x= 4 --> 5(4)-14= 20-14= 6, therefore y=6 CORRECT
If x= 7 --> 5(7) -14= 35-14= 21, therefore y=21 CORRECT
